To all whom it may concern:

Be it known that I, VINTON E. SIssoN, residing at Chicago, county of Cook, State of Illinois, and being a citizen of the United States, have invented certain new and useful Improvements in Corrugated Walls for Railway Cars, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and to use the same, reference being had to the accompanying drawings, which illustrate the preferred form of the invention, though it is to be understood that the invention is not limited to the exact details of construction shown and described, as it is obvious that various -modifications thereof within the scope of the claims will occur to persons skilled in the art.

The ends of railway cars are subject to considerable stress due to the shifting of the lading which is caused by the heavy locomotives, the automatic air brake, the hump and other modern railway service conditions. These thrusts may be local, tending to distort the end insome particular spot, as, for example, when a piece of piping or lumber shifts lengthwise, or a load of plastic material, such as grain, sand or chats may shift, imparting a blow over a large area of the end wall, whereas rail, steel plates, castings and the like cause blows at the bottom of the car. From the above, it is apparent that a railway car and must be strong throughout its entire area. Experience shows that a stronger end wall is needed adjacent the floor of the car because the blows against this portion of the car wall aremore frequent and more severe than at the middle or upper portion thereof. Very little strength is needed adjacent the top of the car wall and the strength required at the middle of the car wall is more than needed at the top and less than needed at the bottom. Furthermore, considerable more strength is required at or near the vertical middle of the wall than adjacent the sides of the wall, because the side portions are held in and supported against a shifting lading by the side walls of the car. Also plastic ladings, such as sand and grain, have a greater tendency to shift at the middle of the car than elsewhere.

While, of course, eft'orts are made to block the lading in the car, the shocks caused by the heavy locomotives, the emergency air brake and the classification hump tear the lading away from its moorings and throw it against the side walls of the car.

A rigid end to a car, and particularly a large car, materially strengthens the entire 1 superstructure to resist the torsional and weaving movements which not only rack the car to pieces, but cause leaky roofs and inoperative and leaky doors with their consequent damage claims. As it costs as much to transport a ton of freight car as it does a ton of lading it'is imperative that the weight of the car must be kept as low as possible, therefore, the end must be very light as well as strong. As freight cars are frequently damaged in wrecks and byother unfair usage, any end will probably be damaged in service, therefore, it must be capable of being easily repaired with such meagre facilities as the railroads are equipped with at their outlying repair points.

My invention relates to the construction of railway cars and more particularly to metal end structures or walls for railway cars made of one or more metallic plates or panels formed with integral reinforcing stifl'ening or, bracing corrugations. ever, the construction may be used in car side walls. It is readily adaptable to box, gondola, stock or other types of railway equipment. 1

Allmetal car ends have been made of corrugated metallic plates secured together having the centers of adjacent corrugations equally spaced apart. I

One of the objects of my invention is to provide a metallic end wall made of one or more metallic plates with reinforcing corrugations or panels formed therein wherein Another object of myinventionis to space the corrugations so that the end wall is strengthened according to its requirements, but at the same time, the corrugations are maintained at the same depth throughout Howthe entire end wall. This has the advantage of not increasing the length of the car over the end wall or decreasing the inside length of the car. The thickness of the end wall is maintained constant throughout.

. A further object is to provide. a corrugated metallic Wall element which it is practically possible to manufacture and easy to apply and secure to .theicar.
